My game doesnt launch in my device

when i click on my game in my device it wont open and after 5 seconds it says unfortunately, (ProjectName) has stopped. i am using the samsung note 2 and the Android version is 4.3 maybe is that the problem?

there is many reason that cuz that , since I’ve no idea about ur project, but it could be permission issue , like trying to start voicecapture and no mic permission and thus the app will crash .
